Specification of Letters Patent.

Patented July 25, 1911.

Application filed March 4, 1910. Serial No. 547,278.

To all whom 'it may concern:

Be it known that we, BENJAMIN F. PEE'rz and HIBBARD S. MCDANEL, citizens of the United States, and residents of Moro, in the county of Sherman and State of Oregon, and NELSON W. THOMPSON, a citizen of the United States, and a resident of Portland, in the county of Multnomah and State of Oregon, have made certain new and useful Improvements in Copy-Holders, of which the following is a specification.

Our invention relates to copy holders for typewriters and it consists in the combinations, constructions and arrangements herein described and claimed.

An objectof our invention is to provide a copy holder in which the copy may be fed forwardly by the mere act of operating the typewriter machine.

The invention relates more specifically to novel means for effecting the feed of the copy in which the feed mechanism may be operated by the movement of the typewriter itself, or manually if desired.

The mechanism for holding the copy, which is. disclosed herein, will be made the subject of a divisional application.

Other objects and advantages will appear in the following specification and the novel features of the device will be particularly pointed out in the appended claims.

Our invention is illustrated in the accompanying drawings in which similar reference characters denote like parts in the several views, and in which- Figure 1 is a perspective view showing one embodiment of our invention. Fig. 2 is a vertical section through the device showing its application to a typewriting machine. Fig. 3 is a plan view showing the adjustable base. Fig. 4 is a front view of a portion of the device. Fig. 5 is a section along the line -5-5 of Fig. 4. Fig. 6 is a section along the line 6 6 of Fig. 7. Fig. 7 is a section along the line '7`7 of Fig. 6, and Fig. 8 is a perspective detail view of the adjustable shield.

In carrying out our invention we provide a base consisting of the members 1, 2, 3 and 4. Each of these members is provided with a recess 5 into which the feet of the typewriter are ada ted to be placed. The member 3 is provi ed with a lateral supporting arm 6 which bears a cylindrical extension 7.

The members 1 and 2 are adjustably connected by means of a pin 8 secured in one f the parts and adapted to slide back and forth in a. recess in the other. The members 4 and 3 are similarly connected by the pin 9. The members 1 and 4 are loosely mounted on a rod 10 while the members 2 and 3 are mounted on a similar rod 11. The latter has a smaller rod 12 extending through its interior. On the rod 12 is a collar 14 which is adjustable longitudinally of the rod and which may be rotated around the rod and fastened in any position by means of the arm 13 which may be screwed up against the rod 12. The end of the arm 13 projects underneath the stem 15 of a key 16. On the opposite end of the rod 12 is a rock arm 17 which is pivotally connected to a. link 18 which is adapted to operate the feeding mechanism in a manner hereinafter described. It wil'l be seen that the base members may be adjusted to tit a typewriter of any size.

Screwed to the rear ends of the rods 10 and 11 are the uprights 19 and 20 respectively which bear at their upper ends the base 21 of the copy holder proper as shown in `.F ig. 2. The base 21 has secured at each end of it the side members 22 and 23 see Fig. 1. The member 22 is perforated to provide a bearing for the shaft 24 of the main copy holder roller 25, see Fig. 7. This roller is provided near each end with enlarged portions 26 having resilient coverings arranged to coperate with the Y ressure rollers 27 above the main roller an rollers 28 below the main roller. The rollers 27 are loosely mounted on a shaft 27, while the rollers 28 are loosely mounted on a similar shaft 28", see Fig. 1. The members 22 and 23 each bear a pair of sliding plates on their inner sides and a description of one set of lates will suilice, since the plates on the ot er member are precisely the same. Considering then, the member 22 shown in Fig. 5, it will be seen that there is a plate 29 immediately next to the member 22 which is provided with a slot 298L at its lower end. Another plate 30 is inside of the plate 29 and adjacent to it and is provided With a slot 30 at its upper end. From an inspection of Fig. 5, it Wlll be seen that the plate 30 is provided with an opening 30". A guide screw 31 is carried by the lower' portion of the inner plate 30 and is adapted to extend through the slot 29d in the plate 29 and also through a registering slot 22X in the side member as shown in Fig. 5. The plate 29 bears the shaft 27fL on its upper end which is reduced so as to pass through the slot 30a of the inner plate and which may also extend through a registering slot 22a in the member 22. The shaft 23a extends through the openings 29b and 30 of the plates 29 and 30 respectively. Secured to the end of the shaft 28a are the cams 29c and 30C. These cam members are disposed in the openings 29b and 30b of the respective plates 29 and 30.

1n Fig. 1, we have shown a lever 32 for rocking the shaft 28a and thereby causing the cam members 29C and 30 to move the plates 29 and 30 in opposite directions. A similar arrangement of cams is provided at the opposite ends of the shaft 28, and hence the operation of the lever 32 will cause the pressure rollers operated bthe shafts 28 and 27 to leave the main ro 1er, as when the paper containing the copy is to be inserted or withdrawn, or for an other reason.

As will be seen from Figs. 1 and 5 a downward movement of the lever 32 will cause the cam 30c to push the plate 30 downwardly, while the cam 29e will push the plate 29 upwardly. The shaft 27L will be carried upwardly with the plate 29. As soon, however as the shaft 27 reaches the limit of the slot 22, the movement of the plate 29 will be stopped, and the further revolution of the shaft 23a will cause the cam 29c to move the shaft 28L downwardly. Thus, it will be seen that both of the shafts 28a and 28C', together with their lpressure rollers will be moved away from t e main roller. A spring 33 which is connected to the arms 29d and 30 respectively tends to hold the ressure rollers close to the main roller. *ach of the plates 29 and 30 is provided with a slot similar to the slot 30e through which the shaft 24 of the roller 25 extends so as to allow a free movement of the plates.

On the outer side of the member 22 is secured a casing 34, s'ee Fig. 1, which contains the main actuating mechanism of the copy roller. The construction of this mechanism is best shown in Figs. 6 and 7. i

Referring now to Fig. 7, it will be seen that the shaft 24 of the roller 25 extends through the member 23 and loosely bears a member 35. The member 35 is provided with teeth 37 on one side and is grooved on the opposite side for the reception of a spiral. spring 38, which is secured at one end to the member 35, see Fig. 6, and at the other end to a segmental shield 39 of the form shown in Fig. 8. The shield is provided with a flange 39EL which lies between the casing134 and the periphery of the member 35, see *i0 7, and-the shield may be moved in this concentric runway by means of a thumb screw 40, but it may be locked in its adjusted p-ositions by means of a set screw 41 which engages in the notches 42 in the periphery of the shield. A ratchet wheel 43 is secured to the shaft 24 by means of the set screw 36. A pawl 44 is pivotally mounted on the member 35 and is held in normal contact with the ratchet 43 by means of a spring 45, see Fig. 6.

Arranged to coperate with the segmental gear 37 is a rack 46 which is provided with a lateral arm 47, see Fig. 1, arranged to pass through an opening 34x in the casing 34 and adapted to be engaged by a lever 48 which is pivoted on the member 23 and whose end is connected with the link 18. end of the rack member 46 is provided with a cam roller 49, see Figs. 1 and 4.

Referring now to Fig. 1, it will be seen that the base member 21 is provided with the extensions 21a and 21". These extensions sl idably support a hollow bar 50 which has a telescopic member 51. The latter is provided with notches 51, see Fig. 4, arranged to be engaged by the end of the spring controlled pin 52 which is carried by a cylindrical arm 53 secured to the bar 50. The pin bears a circular head 54 by which it may be manipulated. The rod 50 is acted on by a spiral spring 55 which is secured at one end of the base 21. The rod 51 bears on its end a laterally extending arm 56 provided with a resilient end member 57. rl`l1e rod 56 may be adjusted in the direction of its length by meansof the screw 58 or it may berotated around the screw 59 as an axis by loosening the latter. The tightening of this screw holds the arm securely in its adjusted position. The rod 50 bears on one end an -L-shaped support 60 to which is pivoted the cam 61. The free end of the latter rests loosely on an adjustable pin 62 carried by the bar 50.

From the foregoing description of the various parts of the device the operation thereof may be readily understood.

In using this device the base members 1. 2, 3 and 4 are adjusted to fit the feetf63 of a typewriter 64 as shown in Fig. 2. The key 16 will then be adjacent the keys 65 of the typewriter. The rod 56 is then adjusted so as to be adjacent some portion of the typewriter carriage when the latter is near the end of its return movement, This may be accomplished by manipulating the spring actuated pin 52 and adjusting the rod 51 and also by adjusting the rod 56 upon the rod 51 in the manner already described. The paper containing the co y may be inserted between the paper guide 66 and the main roller 25. The roller may be turned by means of the thumb wheel 67 so as to feed the paper in. Now by pressing down- The lower.

wardly on the lever 32 the pressure rollers are separated from the main roller and the paper may be passed between them. The thumb wheel 67 may then be turned until the paper is brought to the pro er place. It will be noted that as the thum wheel is turned the ratchet wheel 43 is turned idly, the pawl 44 riding over the teeth of the ratchet. The paper is now in position for copying and the return movement of the typewriter carriage carries the rod 50 along with it. The inclined cam 61 engages the roller 49 and the rack is lifted thereby as the typewriter carriage continues to move. The upward movement of the rack causes the revolution of the roller 25 through the medium of the pawl 44 and the rack 43. The roller 49 rides over the pivoted end of the cam 6l and the rack descends, the end of the pawl riding over the teeth of the ratchet as the member 35 is rotated. The roller 49 moves downwardly behind the pivot of the cam (S1, and in the next forward movement of the carriage this roller slides beneath the cam 61, and by raising the cam it is enabled to pass between the cam and the pin 62.

In the position in Fig. 6 the shield is adjusted so as to permit a maximum line spacing. If a shorter distance is desired the screw 4l is loosened and by means of the screw 40 the shield is shifted to the next notch 42. The lower end 39 of the shield, see Fig. 6, now holds the pawl 44 free from the ratchet until the pawl is moved far enough to clear the end of the shield. It will be obvious that not as great a movement of the ratchet will occur as when the pawl is always in engagement with the ratchet teeth. Various adjustments of line spacing may be had by setting the screw 41 in different notches.

In case the operator should Wish to shift the copy a definite number of lines without moving the typewriter he may do so b, depressing the key 16. The depression o1Y this key will cause an upward movement of the lever 48 and hence of the rack and will result in turning the copy roller a definite amount. Thus one depression of the key may turn it two spaces and another four spaces so that by working the key the copy may be brought to the line desired.
